I’ve run into the issue described in github, and as it closed as “non-specific to this project”, I just thought I’d post this here also, so people can find it easier and for discussion between resin and the community

Are there any timeframes set for this feature? I’m fairly sure it’s an essential development for multiple applications (of course including mine ).

As far as I know the feature is implemented, but not yet deployed due to some not yet resolved conflicts with other parts of our stack. We actually want it almost as much as you
I’ll get back to you as soon as we have any schedule for deployment.

We have made significant progress in supporting WebSocket during the past weeks. This means that you will soon be able to use your library of choice (e.g. socket.io) to create real-time resin apps that will be accessible from the public device URL.

Our infrastructure has been upgraded to include this feature and we are in the process of testing it in our staging environment; this means that we plan a release in the coming days, so stay tuned for the announcement.
